similar thing happened to one of mine.
Honestly I can't remember which glue I used. Sorry.
Might have been some rubber/contact adhesive I had lying around.... or something else?
Mine too was under warranty at the time, but two minutes to crawl under vs appointment, driving to the dealer...arranging for my wife to pick me up..... no thanks.
Go to your local hardware and find a fairly aggressive glue that's ok for plastics and elastomers....
